I will be working on a place known as "Neltharion's Heart/Murloc's Paradise". It would take place in one of the new dungeons, the one known as "Neltharion's Lair". I did some research and it seems to be the place in which Neltharion used to habit before it became Deathwing (according to WoWPedia).

This would be the place in which players would be able to upgrade their weapon into a fire/lava looking weapon after defeating the last boss in the dungeon.

"A gigantic anvil, known as Neltharion's Heart, made out of a thousand dragon scales. The anvil is suspended by huge chains and is infinitely pouring lava!Lava/fire Murlocs enjoy having parties and looking up to the anvil like some sort of God! Little they know that the anvil is one of the few anvils that carry the strongest powers in the world!"

I will post a sketch soon as I am not so good with words haha! And sorry if I am not getting the lore correctly hardcore WoW fans! I haven't played WoW since the Burning Crusade!

Edit: polished the whole idea one last time before starting to work on the concept art ! Edit#2: changing the idea a bit more to make it less serious lol. RwlRwlRwlRwl...etc etc.Trying to make a submission that is more on the funny side of Blizzard's style.
